Wifi's Internet disconnecting on my laptop?!

Router: Linksys EA3500
Network Card: Broadcom 4313 Wireless -N

iwconfig NOT WORKING

          Mode:Managed  Frequency:2.452 GHz  Access Point: 20:AA:4B:75:69:0A

iwconfig once I reconnect

Ive turned QoS off on my router in hopes my laptop would do that same, however didn't fix anything :I(

Just a heads up the icon says I am still connected to the network however the internet doesn't work, neither does accessing my 192.168.1.1


Also this seems to be a problem with gnome-shell, as I just switched my laptop over from i3 tiling and never encounter any problems with the wifi

Re: Wifi's Internet disconnecting on my laptop?!

I know nothing about wireless, just wanted to mention, that a few  other users seem to have issues: https://bbs.archlinux.org/viewtopic.php?id=149971 (Broadcom), https://bbs.archlinux.org/viewtopic.php?id=149964

Re: Wifi's Internet disconnecting on my laptop?!

Maybe I'm missing something.  Why do you assert that iwconfig is not working?  It appears to me that, in both cases, you are associated with an open access point called PwNz with a MAC address of 20:AA:4B:75:69:0A.  This is the wireless equivalent of plugging in the cable.

I am guessing you missed the next step, which is to go and get an IP address.

What is the output of sudo ip link  ??
Then, what is the output of ip addr  ??  I'll bet one credit there is no address shown for your wireless device.

If the first ip command shows your wireless interface, but the second does not report an address, I win smile

If that is the case, try sudo dhcpcd wlan0  (or whatever your interface is called) and you will probably be good to go.

Re: Wifi's Internet disconnecting on my laptop?!

Alright I will wait for it to disconnect and then try those commands. I figured it has to be gnome because the issue only appeared after switching from i3 tiling to gnome-shell w/ systemd.

the nm-applet tray icon still says there is a signal and is connected by appearance but when you try and access a website or internet service it times out or is unreachable, I just quickly disconnect and reconnect the wifi adapter and it works again... lol

Also its a WPA2 encrypted access point not open haha, I think that might be the problem as it reports encryption key: none even though I login to it using a WPA2 key...

Heres the Results

sudo ip link

       valid_lft forever preferred_lft forever

sudo dhcpcd wlan0

dhcpcd[12989]: dhcpcd already running on pid 12857 (/run/dhcpcd-wlan0.pid)

Did it give you any information that might help me out?
*note these were taken while my network said it was connected but the internet wasn't usable.

Re: Wifi's Internet disconnecting on my laptop?!

You have a connection and you have an IP address. Are your routes setup (what is the output of `ip route`?).
Also, somehow dhcpcd is getting started. Are you using NetworkManager (what daemons do you have enabled)?

Re: Wifi's Internet disconnecting on my laptop?!

I think stebalien is correct.  It seems very much like a route issue.  Especially since you cannot ping 192.168.1.1.    Can you ping 192.168.1.112  ?
Also, we might want to try disabling IPv6 for the time being.   https://wiki.archlinux.org/index.php/IPv6#Disable_IPv6
